Welding steel pipe production and market offer

After three industrial revolutions, steel pipes such as erw round steel tube have been indispensable in many industries. In the initial stage of the application of steel pipe, there are many applications of seamless steel tube because of the some requirements from industries for the quality of steel pipes. However, the production process of seamless steel tube is more complex and the production cost is also very high, which is far from the satisfactory for customers. Although the price of welding steel pipe is relatively low and the production process is relatively simple and convenient, it can’t meet the demands of customers in terms of pipe quality sometimes. With the continuous development and progress of welding process, the quality of welded steel pipes is getting higher and higher.

The types and applications of welded steel pipe should be introduced firstly. Welding steel tubes can be divided into electric tubes, furnace welded pipes and gas welding pipes according to different welding methods. If the classification is welding process, it can be divided into straight seam welded pipe and spiral seam welded pipe. The difference is between straight line and spiral angle. The straight seam welded steel pipe has become more and more popular among customers because of its simple production process as well as lower production cost. When it comes to pipe shape, the major shape is round and square.

Welding steel tubes are widely used in many industries, such as chemical and petroleum industries. The application can be summarized into two aspects, one is transportation such as oil, natural gas, the other one is for building materials such as round steel pipe which can guarantee the stability of the structure and save the cost.

There are many kinds of welded steel pipe specifications, which can be applied to different situations. For example, for the straight seam welded steel pipe, the size ranges from 1 inch to 6 inches and the thickness varies from 2 mm to 3.25 mm. As the factors have reflection on steel pipe price, steel pipe market is always unstable, which have a high requirement for the steel pipe manufacturers in grasping new market trends. The factors include government policy, steel pipe market situation as well as competition factor. In a word, the steel tube market is facing opportunities and challenges as well. Steel pipe manufacturers should give full play to their distinct advantages to seek for more market shares.
